HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS The IDT7132SA55J is a high-speed 16K x 8-bit dual-port static RAM (SRAM) manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Memory Size:** 16K x 8-bit (131,072 bits)
- **Organization:** Dual-port, independently accessible
- **Access Time:** 55 ns
- **Operating Voltage:** 5V ±10%
- **Operating Temperature Range:** Commercial (0°C to +70°C)
- **Package:** 48-pin PLCC (Plastic Leaded Chip Carrier)
- **I/O Compatibility:** TTL-compatible inputs and outputs
- **Power Consumption:**
- Active: 750 mW (typical)
- Standby: 55 mW (typical)
### **Descriptions:**
- The IDT7132SA55J is a dual-port SRAM that allows simultaneous access from two separate buses, making it ideal for shared-memory applications.
- It supports fully asynchronous operation for both ports, enabling independent read/write operations.
- Features include automatic power-down and interrupt flag generation for port arbitration.
### **Features:**
- **Dual Independent Ports:** Allows simultaneous reads/writes from both ports (except same address).
- **Bus Arbitration Logic:** Includes semaphore flags for inter-processor communication.
- **High-Speed Operation:** 55 ns access time for fast data transfers.
- **Low Power Consumption:** CMOS technology for reduced power usage.
- **TTL Compatibility:** Ensures easy interfacing with standard logic devices.
- **Automatic Power-Down:** Reduces power consumption when not in use.
- **Interrupt Support:** Provides flag signals for port contention resolution.
This device is commonly used in multiprocessor systems, communication buffers, and other applications requiring shared memory access.
